In this work, by using an extraordinary transmission metamaterial prism and taking advantage of its inherent dispersive behavior, the feasibility of manufacturing a demultiplexer/multiplexer or even a spectrogram analyzer at millimeter-waves is shown. Depending on the incoming beam frequency, the outgoing beam suffers in a wedge-shaped configuration a different deflection (governed by Snell's law). Since the frequency dependent index of refraction of this metamaterial can go from negative values to almost zero for the first propagation band (cut-off regime) and also be positive for the second propagation mode (non-cut-off regime), different negative and positive outgoing angles can be obtained and then, diverse paths for each frequency, as the Fresnel zone experimental results confirm.
